Enclosures of Series Motors Totally-enclosed Fan-cooled Type (CACA) Series Output : 50Hz 160 ~ 2,800KW (210~3,750HP) 60Hz 200 ~ 3,550KW (270~4,750HP) Voltage series in detail : 2,300V ~ 11,000V Insulation Class : F Class Apply Standards : IEC, NEMA, BS, AS ... In an environment containing corrosive or harmful gas, a totally-enclosed fan-cooled motor (IP44 / IP55, IC611) is generally used. The external fan mounted on the opposite drive end directs fresh air into the pipes of the air housing located on the upper part of the motor. The pipes constitute a heat exchanger in which fresh air passing through the pipes cools motor inside hot air. HEAT EXCHANGER STATOR CORE EXTERNAL FAN COVER NEMA Weather-protected Type-II The open-outdoor type motor (IP24W, IC01) is a motor used for outdoor that incorporates an air housing in accordance with NEMA WPII. It includes three right angled turns for air inlet and inlet air duct has a section where wind velocity falls below 3 m/sec (600ft/min.), dripping water, dust, and foreign materials. A section is provided in which air may blow through without being forced into the motor. Drip Proof Type A drip proof type motor (IP22, IC01) is a common choice for a well ventilated room. Cooling air intake and hot air exhaust windows are located at top hood portion. The ducts are windows provide with separate braid at inside and screens at outside to prevent intrusion of water drips and other foreign materials into the motor inside (NEMA WP- I requirements). Totally-enclosed Air-Water-cooled Type (CACW) This type of motor (IP44 / IP55, IC81W) is especially useful in a location where low noise operation is required or where it is desired to remove heat from the motor ambient. The motor accommodates an air to water heat exchanger in the air housing in the upper part of the motor. A drain in the air housing protects the motor proper from damage caused by water leakage. BEARING COVER ROTOR CORE BEARING COVER AIR DEFLECTOR EXTERNAL FAN COVER INTERNAL FAN BEARING HOUSING BEARING HOUSING BEARING BRACKET BEARING BRACKET Fundamental IC01, IC61 and IC81W per IEC Standard constructions are available by changing top hood construction, in addition to the four type where described here. Main terminal box can be changed every 90 degree angle. Main terminal box size is large enough to connect cable easily. And also provided shaft current protection insulator at none drive end bearing portion for 450 frame and sleeve bearings machine as standard.
